It's easy to add ctime to ?action=attr, the hard part is having
something that can convert dates and times into unix timestamps.
(Especially since whatever we use needs to be re-usable for many
date+time conversions in PmWiki, not just this one application.)

To just add ctime to ?action=attr:

    $PageAttributes['ctime'] = '$[Set page creation time:]';

This at least allows a person to enter a new timestamp, but
it doesn't handle conversions well (I'm still thinking about
that issue).  One simplistic way to do that might be to do the
following in local/config.php or a recipe:

    if (@$_POST['ctime']) { ...code to convert ctime here... }

Of course, one could always create an ?action=ctime that allows
the ctime to be set directly (and defaults to requiring 'attr'
permission), thus

    .../pmwiki.php?n=Main.SomePage?action=ctime?when=2006-07-18

could be used to change a page's ctime to a different date
without having to go through a form.  More likely would be
to come up with an extensible form of ?action=postattr,
which given things like:

    .../pmwiki.php?n=Main.SomePage?action=postattr&ctime=2006-07-18
    .../pmwiki.php?n=Main.SomePage?action=postattr&time=2006-07-18
    .../pmwiki.php?n=Main.SomePage?action=postattr&title=....

would be able to call special "hooks" for each attribute to
be set.
